Abstraction
Abstraction in computer programming is a way to reduce complexity and allow efficient design and implementation in complex software systems. It hides the technical complexity of systems behind simpler APIs.
Advantages of Data Abstraction
- Helps the user to avoid writing low-level code.
- Avoids code duplication and increases reusability.
- Can change the internal implementation of a class independently without affecting the user.
- Helps to increase the security of an application or program as only important details are provided to the user.
Example
js
class ImplementAbstraction {
// method to set values of internal members
set(x, y) {
this.a = x;
this.b = y;
}
display() {
console.log(`a = ${this.a}`);
console.log(`b = ${this.b}`);
}
}
const obj = new ImplementAbstraction();
obj.set(10, 20);
obj.display();
// a = 10
// b = 20
